Johan's evocative series Evidence of Things Seen depicts children who seem focused on ordinary play, yet something appears amiss in their world. These large-scale, vividly colored compositions created from multiple negatives explore the emotional isolation and psychological vividness of childhood. This eerie narrative placed in an urban setting was produced by digitally combining three separate negatives. Two were studio shoots, one of a blonde-haired girl whose body was replaced with a photo of a similarly attired boy. The backdrop was an outdoor shoot of a snowy cityscape. Describing the scene, the artist explains, "The girl sees something magical, and has a camera ready."
